updating Browser
My Linux/Computer guru passed away 5 years ago I have been using Firefox Quantum 57. 0.4 64 bit for Linux Mint 1.0 but am finding sites I need to access won't open or if they open can't use the functions there. I know nothing about computers and I have not been able to find a tech to take my desktop to to get it updated. I am afraid to update because computer is currently set up with protections so I can do banking etc.. but soon I won't be able to access that. Any suggestions as to what to do at this point or suggestions of tech's in the Far West Valley of Phoenix AZ to assist ? Thanks so much for your time and any suggestions. Cheers,
